kTo all whomz'tmag/ concern.' i i f Be it known that LQCriARLns'VoGT, a1citizen of the United States, and a resident of Chicago, in theV county oiV Cool; and State of Illinois, have invented -`afneiv and useful Improvement Vin Locking Devices, of wh ich exactv y p p -f 2. ,A lockingringV or bushing 3 is threadedl the .following is a full, clear, and Y, description.

' My invention relates to devices for coupling tubular members together, and itconsists in the combinations, constructions, and,k

arrangements hereindescribed claimed.

An object of my invention is to provide an improvement over the locking-device dis-V 15 closed Vin my prior application `for Patent,

Serial No. 472,514., filed :May 25,1921, said improvement consisting in the provision of 4a locking device operable to occasion the*k locking et connected members againstmove-. ment relativelyfin one direction, while per-` mitting` tree movementthereot in the opposite direction.l y l y K A further object ot myinvention is'to provide a device tor; coupling two tubular members together in alineinent and tornermally preventing the disconnection of they coupled members. Y 'A i'nrther object' of my invention is-fto provide a device Aot the characterdescribed e0 that is key-controlled, secret knowledge as to the adjustment olt tliekey with theV loc-king mechanism to actuatethe locking mechanism so that the connectedmembers may be disconnectedfbeing required.

A Vfurther object' of my invention is to provide a device of the charactergdescribed that is relatively simple inconstruction, not likely to get out vofforder easily, and thoroughly effective; for the purpose -zine0. tended. y i

From the. foregoing description ofY the va:V rious parts of the -device,` the operation thereof may be readily understood. 1n theein- 1 bodiment of the .invention illustrated, Y show the device applied'to an Vautoinobile radieter.

.on the filler tube 2 las a unie it will be manifest that the pin 1,3 will be carried by' c the member andwill swing slightly aboutY 25l 10 of the. lockin` ring'f se that they willA 4not bind the liller tube 2,whenl the eap l5 Y isV being turned clockwise. `rlie expandedl ring `'will 2grip the member 5 and will'ro-VV i These openings are'threadedfor engagethe groove 14 als .a pivot, thereby v"moving the relatively narrow end portions 9 and .groove 141 ,inthe reverse direction and Vwould inovevthe relatively narrow end portions 9 y'fa-ndi() relatively to one another s uii'iciently to exert a binding action on the threads ot Ythe filler tube 2 and to preclude movement of the couplingmemberA 5. The contraction .of the ring about the tube vQ'fpreventsvthe ring' from rotating with the member 5. The member 5 is secured to the ring by the pin,

and `in being` rotated anti-Clockwise `will cause the pin to bind the ring` more firmly `on vthe tube..

`'llhecouplinpT member 5 is 'fashioned with Va"plurality oft openings 16 arranged lto extend radially through its wall. as shown.

I vljllien thekey 17 4has been projected vinto the :opening 16 that registerswith the openinfif'itl,` theenggement of the end portion he "cap, coupling mem- :or the key with the endv portion '10 of the locking ring 3 will lock thering to the inem- 5 se thatinc swinging of the pinl?) will result when the niemberv is rotated. The

Vpin therefore will'not cause rthe-ring to bind upon the -tubey and in consequence7 the coupling;Y member 5 may be turned freely inr either'direetion. The severa-l openings 16 )may be appropriately. marked vin any suitable manner 'sot-hat authorizedA persons may vinstarit-ly 'project the key 17 into operative vposition lwith .wliile unauthorized persons will have no respect tothe locking ring v3,

.means or knowing when the key 17 has-been placed in the proper o iening. The device is thereiore particularly well adapted for applic fion to radiator filler tubes in order to preisen:u ene theft or Vaccidental displacement the radiator capsthererom.

' ei'ferringnew to Figures 3 and 4C of the drawings,V l show a slightly di'erent form embodying Vthe saine invention7 :is-applied to :in interiorly 'threaded iill'er tube iO-of a radiator 3l.Y A locking ring 32 is split'to provide relatively narrow aimed. end por- Vtions 33 and 311. `The lockingjr ring,Y 32 is threaded interiorly for engagement with a coupling' member 35 and is threaded ente "riorly for eneagement vwith the vinteric'irly vthreaded iiller tube 80. The locking ring 32 lis providedy with an outwardly extending annulariiange y'thereby defining a shoulder.

Si' against which the upper end of thetiller tube abuts when'the couplingr member 35 has been inoved into the position illustrated. The. coupling inember isflenlarged adjacent to its upper end to provide iiange ranged to overlie the upper end of the i -tlange 36. An opening 39 through the flange 88 registers with a socket il() in the locking` ringf AS in the torni oft the de- `vice illustrated in Figure 1,tlie'socket 40 yextends through the end portion into the adjacent wallet the end portion '33 and is adapted to loosely receive a pin 41. The latter protrudes from the socket 110 into the bore 39 and ismaintained in place by a screw 4t2.Y Thepin 41k is fashioned with an annulargroove 43 in the portion thereof interpose i13913116131115h61 adjacent walls olf' the `end portionsBB andfSt of the looking ring. The coupling member 35 is permanentlyse-VK `cured lte ak radiator capy le by means yof rivets 45 o r any other'suitable `known means.

The operation of the form of the device illustrated in Figures?) and 4' is identical in essential respects with the operation of the form of the` device illustrated Viii-Figure 1,*which has already'been described. The

.key 17 may be projected through any one of the series of openings 46 in the locking ring 32 until 4the reduced end portion 18 of' the key4 is disposed within a registering socket 4 7 in the coupling member 35.v Only oneofcthesockets 47 is adapted to closely rit the rediiced end portion vl8'o the key The lrey musttherefore beprojected into the proper socket in order thatthe coupling member 35 may be displaced from ythe fillerv tube 30. A n Y l claim: I LA device of the characterl described comprising a split locking'ring fashioned threaded for connection with al tiiblarmember, an additional tiibiilar4 member threaded to provide cooperating relatively narrow end portions, said locking ring being for-connection withl the split locking` ringl and having a portion thereofarranged to` overlie the end of the locking ring, and

- means projected through registering openings in the overlying portion'of the ylast named tubular memberfand inthe adjacent end portion of the locking ring into a socket in the adjacent wall of the other. endportion for limiting the movements ofthe said end portions relatively to vone another.
